New Fossil Find in Ethiopia Reveals Paranthropus' Northern Expansion and Ecological Adaptability
  • The finding prompts reevaluation of hominin biogeography, adaptation, and competition, potentially reshaping understanding of Paranthropus' evolutionary trajectory and its relation to Homo.

  • Experts note this discovery highlights the complexity of early hominin niches and the need to revise how key differences among early groups are understood.

  • The Mille-Logya find places Paranthropus within a diverse hominin mix in the Afar (~2.8 to 2.5 million years ago), prompting questions about interactions with Australopithecus and early Homo.

  • A new fossil discovery at Mille-Logya in the Afar region of northeast Ethiopia extends the known range of Paranthropus, showing they inhabited more northern and varied environments than previously thought.

  • The find supports the idea that Paranthropus could adapt to grassland expansion by shifting diet toward grasses and other resources, indicating ecological versatility beyond a fixed woody-habitat model.

  • This discovery sheds light on Paranthropus' environmental adaptation, broader geographic distribution, and possible interactions with other hominins, including Homo.

  • Researchers led by Zeresenay Alemseged used micro-CT scanning to analyze the partial jaw and internal morphology, blending field recovery with advanced imaging.

  • The study appears in Nature (2026) with DOI 10.1038/s41586-025-09826-x, authored by Alemseged and colleagues.

  • The jaw specimen, designated MLP-3000, comes from an older individual and shows dental and bone traits consistent with Paranthropus, the so-called robust hominins.

  • The wider dispersal of Paranthropus suggests multiple hominin lineages coexisted, supporting a mosaic view of human evolution rather than a single linear progression.

  • There are indications Paranthropus may have used simple stone tools, along with evidence of a highly dexterous hand, suggesting greater tool-use capability than previously recognized.

  • A 2.6-million-year-old lower jawbone and accompanying molar crown affirm the specimen as Paranthropus, likely P. aethiopicus or P. boisei, making it among the oldest Paranthropus remains.
